EARTHWORKS LN JOYDENS WOOD, BEXLEY,
KENT.
BY A. H. A. HOGG.
JOYDENS WOOD lies about 1£ miles to the south-east of
Bexley, to the east of the river Cray, on a hill of sandy gravel
rising to about 250 feet above Ordnance Datum. It has
long been known to contain many deneholes associated with
banks and ditches. Most of these seem to be the remains
of a farm site, probably medieval, and its associated fields,
lying at the junction of two ancient tracks. To the west
there is a dyke, probably of earlier date, facing towards the
Cray valley. Little excavation has been done, and relics
are scarce, but in spite of this the remains are of interest.
The farm site is unusually complete and well preserved
owing to the absence of later disturbance, and provides a
useful indication of the character of mediaeval agriculture
in this area. It would be unwise to generalize without
further work on other sites, but it may be noted that strip
lynchets, generally regarded as typical of the early mediaeval
period in most of southern England, are decidedly rare in
Kent, and it seems possible that the Joydens Wood type
of site may have been more usual. The dyke belongs to
the group of " grimsditches " partly surrounding London,
and is the only one in which any excavation has been carried
out. It is also mentioned in a ninth century boundary
survey which is itself of interest and which has not previously
been worked out in detail.
Only two accounts of the site which are of any value
have been published, and neither deals fully with the remains.
F. C. J. Spurrell has published a plan1 on a scale of approximately
6 inches to one mile, together with a short description,
in his paper on " Deneholes." The plan contains a few
minor errors, but is generally very acourate and complete.

EARTHWORKS IN JOYDENS WOOD. 11
All subsequent general plans seem to have been based on this
survey, and without it the writer's re-survey would have
been impossible. The results of excavations made in a square
•earthwork in the eastern part of the wood during 1925 by
Mr. F. C. Elliston Erwood, F.S.A., have been described by
him in a paper on " The Roman Antiquities of North-West
Kent,"2 accompanied by a new plan of the square earthwork,
and a small scale plan of the other banks, showing a
few in addition to Spurrell's. These papers are referred
to as S and E in the following account.
In addition to the above, a plan of the square earthwork,
with profiles, and an enlarged plan of the other banks based
on S were published by Colonel 0. E. Ruck in 19063 and
there have been a few other minor references.4
From 1924 onwards the eastern part of the wood has
"been sold as small holdings and building plots, but although
much cut up and rendered difficult of access very few of the
banks have been destroyed.
During 1934 the writer re-surveyed the site on a scale
of 1/2500, checking S, both on the ground and from two sets
of aerial photographs.5 On the plan (Fig. 1, reproduced
to 1/7500 scale) those banks which could not be examined
are indicated by a different convention. Deneholes, except
where they occur on lines of bankwhich have been re-surveyed
are based either on the 1/2500 O.S. map or on S. No attempt
lias been made to plan the two denehole clusters, as the exact
distribution did not seem of sufficient importance to justify
the labour involved and a check in Cavey Spring showed
both S and the O.S. map to be incorrect. Stankey Wood is
now built over.
It is clear that the earthworks belong to several periods,
but since these are not always certainly distinguishable it
was decided to prepare a plan showing all banks of whatever
age, and to supplement it by a diagrammatic period plan.
(Kg. 2.)
The remains will be described in the order in which they
seem to have been constructed, with the exception of the
dyke, which cannot be treated without considering other
examples of similar earthworks.

(I.) The earliest remains on the site seem to be the two
tracks AB, CD, which cross at the square earthwork. There
is no certain evidence of the date of the dyke EFGH relative
to these tracks, but it seems reasonable to suppose that their
existence formed one of the principal reasons influencing
the position of the dyke. The track AB generally forms
a slight hollow between two low banks (CD vert. 12-18 ins.),
and seems to have sent off a branch towards Dartford. CD,
except where altered by later banks, forms a very faint intermittent
hollow track. It may be noted that it leads towards
the ford at Dartford, and is unlikely, therefore, to be earlier
than that crossing. Its extension to the south is uncertain.
(II.) The dyke seems to have been the first earthwork
to be constructed, but will be discussed later.
(III.) It seems to have been followed by a system of
agriculture involving the cultivation of small fields and the
use of chalk to fertilize the sandy soil. The remains of this
period fall into two groups, J and K, both characterized by
small banks (CD 12-24 ins.), sometimes forming lynchets,
with deneholes on the line of the earthworks. It seems
probable that it was during this period that the deneholes
were dug on the line of the dyke at FG, and the dyke there
was converted into a lynchet. The most reasonable explanation
of the deneholes is that they provided the chalk to help
the poor lime-free sandy soil. The pits at m seem to be
neither deneholes nor pit dwellings, but are more probably
sandpits, similar to those in Rose Wood, near Ightham.6
(IV.) In the last phase of the occupation of the site the
double square earthwork and the banks (CD ca. 3 ft.)
surrounding the three adjacent fields were constructed.
These banks are later than the track CD, and also overlie,
and in some cases make use of, the banks of group J. The
banks UTF on the west of the old track CD are shown on the
Tithe Award map as the boundary between Baldwynes Wood
and Joydens Wood. On the west of the site these latest
banks cross the small bank LM, which itself is later than the
dyke. LM seems to belong to period III, but the bank
shown connecting LM to group K is very faint indeed, and
it would be unsafe to base any argument upon it.
14 EARTHWORKS IN JOYDENS WOOD,
It is possible that the small inner square NPQR maybe
earlier than the other banks but this is unlikely, for the
corner N is very large, owing to the extra earth which comes
from the ditch at a right-angled corner, whereas Q shows
no increase in size. P and R have both been disturbed.
If the original work had been NPQR, it seems probable that
all the corners would be equally enlarged. It is almost,
certain therefore that NPQR is contemporary with the banks
which touch it. The other banks of this group are certainlyall
of one period. It is clear from the layout of the enclosures
on either side of the track CD that the large enclosures
STUV, XYZ are contemporary, but at first it appears that,
the double square may have been constructed later. It will
be shown below that this cannot be the case. An examination
of the junction T shows that the three banks meeting
there are all of one build. At S the bank ST crosses the.
ditch of the outer square, which cannot therefore be the
more recent. But at V the ditch of the outer square cuts
the bank UV which is contemporary with ST, so the outer
square is not earlier than ST and must, therefore, be contemporary
with it as it has been shown that it cannot be
later. It is suggested in E that WW formed the NE side of
the outer square, but there is no bank on the line WV to.
complete the other side, and WW has more resemblance to>
the banks of period III.
A plan of the square earthwork (Fig. 3) is given on a.
larger scale and shows the arrangements of the internal banks
(CD ca. 2'), and the position of the foundations found. The
small square foundation dry built of flints is that discovered
by Mr. Elliston Erwood. Fifty pieces of medieval potterywere
found near it. The other walls, further to the south,
are exposed in the sides of a small rubbish pit. They are
dry built of chalk and flint, about 18 inches high, and are
accompanied by a layer of thin roofing tiles 18 inches below
the present surface, evidently from the fallen roof. No
complete tile could be recovered, but they are certainly
post-Roman. The absence of scattered building material
suggests that the superstructure was of timber. The ruined
building seems to have been buried by the construction of

the rectangular mound in which it stands, but this is not
certain.
